1 Predicting the risk of Clostridium difficile infection following an outpatient visit: development and external validation of a pragmatic, prognostic risk score  J.L. Kuntz, E.S. Johnson, M.A. Raebel, R.W. Platt, A.F. Petrik, X. Yang, M.L. Thorp, S.J. Spindel, N. Neil, D.H.

2 FIG 1 Failure curves showing the observed risk (solid lines) and the predicted risk (dotted lines) of Clostridium difficile infection during the first year after an outpatient visit among Kaiser Permanente Northwest patients according to deciles of predicted risk, as determined by the risk score.

3 FIG 2 Observed and predicted risk of Clostridium difficile infection during the first year after an outpatient visit among Kaiser Permanente Colorado patients, according to deciles of predicted risk as determined by application of the points-based risk score. The figure demonstrates successful calibration for each decile of predicted risk. For instance, in the top decile of predicted risk, the predicted risk was slightly lower than the observed risk.
